Activity of Antioxidant Defense Enzymes in Rats with Experimental Allergic Encephalomyelitis

Abstract

We studied activities of antioxidant system enzymes in tissues of rats with experimental allergic encephalomyelitis. It was shown that the development of pathology is accompanied by deformation of the neurons and axonal degeneration, intensification of free radical oxidation, exhaustion of the reduced glutathione pool, and multidirectional changes in activities of antioxidant enzymes in rat tissues. The observed imbalance in the antioxidant defense system can be associated with excessive glutathione utilization in the glutathione transferase reaction and different severity of the pathological process in the brain and spinal cord. The received data necessitate the search for compounds that can prevent inhibition of antioxidant system components in order to analyze the possibility of their use in the treatment of multiple sclerosis.
